Secton 18 - Mechancal Components

Platform Level Cylinder

THIS PROCESS REQUIRES SPECIFIC REPAIR SKILLS AND 
EXPERIENCE, APPROPRIATE LIFTING EQUIPMENT AND A PROPER 
WORKPLACE������ DEATH, SERIOUS INJURY OR SIGNIFICANT MACHINE 
DAMAGE COULD OCCUR IF YOU ATTEMPT THIS PROCESS WITHOUT 
THE APPROPRIATE SKILLS AND EQUIPMENT������

The Platform Level Cylinder is located at the end of the inner boom section. Its purpose is to keep the 
Platform level as the position of the Boom changes.

Disassembly

Park the machine on a firm level surface.
Throughout this procedure, thoroughly clean all 
hydraulic connections and tag all hoses for proper 
reassembly before disconnecting them. Immediately 
plug and cap all openings to prevent contamination. 
Tag electrical connections before disconnecting 
them.
Use the Boom Lift/Lower function to raise the boom 
slightly.
Use the Jib Lift/Lower function to lower the jib 
completely.
Use the Boom Extend/Retract function to extend the 
boom approximately 5 feet (1.5 m).
Use the Boom Lift/Lower function to lower the 
platform onto the pallet, then strap the platform to 
the pallet.
Place 750 lbs (340 kg) of weight on the platform 
floor.

Note:

This will prevent the Platform/Jib assembly from tipping when disconnected from the boom.

Remove the hose/cable cover from the side of the 
jib arm.
Clean all hydraulic fittings, then tag all hoses for 
proper reassembly.
Disconnect the hydraulic hoses that supply the 
Jib Lift/Lower Cylinder and the Platform Rotator. 
Immediately plug and cap all openings to prevent 
contamination.
Tag all electrical harness connections connecting the 
boom and the jib, then disconnect.
Remove the bolts securing the platform level bell 
crank pins that connect the bell crank to the boom. 
Secure the Lower Jib Links with a strap, then 
remove the pins.
